1 primal) JOHN w. MULDOON, OF New YORK, N. Y.

COLUMN, Gianna, AND THE LIKE,

To all whom it may concern."

Be it known that-,1, JOHN W. MuLnooN, a citizen of the United States, and a resident of the city of New York, borough of Manhattan,

5 in the county and State of New York, have invented newand useful Improvements in Columns, Girders, and the Like, of which the following is a full, clear, and exact description. v

This invention relates to certain improve ments in reinforced concrete construction particularly adapted for the formation of colum girders, .walls and the like, and relates more particularly to that type of con- .15 s ur-tion. disclosed and claimed in my pre- --""vious'pa tent No; 874,226, issued December 1-7, 1907. In this type of construction, I utilize ametallic reinforcement of such a character that ittserves the double: urpose of holding the concrete in position wl iile it'is hardening, and serves as a reinforcement for the concrete afterit has hardened. I eliminate all'w ooden forms or other supporting means, and utilize the reinforcement as a per- 1 manent form. In theconstructionillustrated inmyprevious patent above referred to, I employ reticulated metal baskets formed of wire netting-orflwire gauze, held in osition y a framework of rods or bars. In t e present construction, I form the reticulated metal 7 baskets of a' plurality. of rods sup orted closely adjacent each other and held so stantially parallel by spacing members extending transversely of the rods. The rods are sufii- 36 'cientlyclose together to prevent the escape ot any material quantity of concreteor cefment therebetween, and serve to present a "roughened outer surface to which a finishingv .coat'will readilyadherq, so as to give the 4o'fgstructure a smoothsurface and conceal and protect the'reinforoement. I also provide certain improvements in the means for spacing the rods in their parallelpbsitions, and the means for holding the baskets ..orcontainers in vertical alinement during the building of a wall or girder, and in the formation of the reinforcement for-thefloors of adjacent Reference is to be hadto the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the figures, and in which- I Figurel is a erspective view of a portion of a structure built up in accordance withmy invention; Fig. 2 is a side elevation of a Specification of Letters Patent. v Application filed April 30, 1908.

In the specific form of reinforcement and retaining means, I em 10y containers each formed of a plurality o rods arranged paral lel and held in their spaced relationship by channel members, which channel members are held in their spaced relationship by longitudinallyidisposed members and held; in 'verticahalinement by suitable connecting members. In the formation of a wall, I ro-. vide substantially the construction i ustrated in Figs. 2, 3 and 4. The specific container herein illustrated comprises two oppositely-dis osed substantially parallel walls detachab y connected together by transverse members, which also serve for holding superim osed containers in vertical alinement.

held rigidly by vertically-disposed channels or channel members 21. The rods'extend through the fiangesof the channel's parallel 'ach wall is formed of a plurality of small rods 20 of any suitable length and i to the web of the channel but spaced a short the body of the concrete after the latter has 1 hardened.

Any number of channel members desired may be employed tor holding the rods substantially rigid and preventing their distortion. All of the rods pass through both flanges of each of the channels which are arranged intermediate the ends of the wall sections, but at the ends of the wall sections,

certain of the rodspass through only one of the flanges of the terminal channel and abut against the inner surface of the outer flange o the channel. The remaining rods extend through both flanges and are provided with terminal nuts 22, orwit-h any other suitable fastening means for holding the parts in their assembled relationship. Where two containers come end to end, one or more of the rods may be made of such length that they will extend. through both flanges of the terminal channel member and also through one flange of the channel n ember of the next adjacent wall section, to b retained therein by suitable nuts 23, as indicated-at the right end of Fig. 2. The channel I'nbmbers are spaced apart at regular distances and are held in their spaced relationship by suitable lo ngitudinally-disposed connecting members. As shown, these members 24 are formed of metal strips in stra form, havin their ends heat at s'ubstantia ly'right ang es to form terminal flanges 25. These spacing members are (ilSPOSE-Ll along the upper and lower edges-of each wall section, so as to form flat su porting surfaces and to space the channelsat both ends. The flanges 25 of the spacing ,frn'ernhers extend alongside .the outer surfaces'of the channels and are of such length 'that one or more of the rods 20 pass there- 'through. The rods hold the spacing members in position, the spacing members hold the channels in pnsitron, and the nutsor other fastening means-22 and 23 on the ends of the rods hold the entire wall section-ml assembled relationship. The side wall sec; tions may be made up inany desired length or height, independently of the thickness of the wall to'be'formed. 4 f

In assembling the containers at the point at which they are to be used, two op ositelydisposed side wall sections are held at the desir d distance 2. )art and substantially rigid in respect to eae other by transverse tie bars. Each tie bar 26 comprises a simple piece of strap metal having terminal flanges I 27 of a width substantially e ual to the distance between. the flanges o the channels and adapted for insertion between the web of a channel and the'rods 20 extending thereto. The flanges fit tightly in place, hold the side wall sections at definite and predetermined distances apart, and byrason of their width and the binding action within the channels, hold the side wall sections against skewing. If desired, two of the transverse tie bars 26 may be placed back to back and rigidly secured together in any suitable manner,'as, for instance,.by rivets 2 8. The transverse tie bars will-then serve not only to hold the wall sections together, but will also serve to hold superim- -posed wall sections in'vertical alinement, as

the flanges 27 of one tie bar would be'in aline s ment with and extending in the opposite direetion from the flanges 27 of the adjacent tie bar. In practice, a majority of the tie bars would be in the simple form, but one or' more of the double tie bars would be used in connection with each container or basket for holding the side walls invertical alinernent.

If desired,tiyotie'bars may bev connected together by suitable links 29, as illustrated at the right-hand end of Figs. 2 and 3. These links in connecting the adjacent tie bars would serve to prevent the longitudinal separation of two containers placed end tb end andact in addition to the nuts 23 of the longer rods.

The container above described and illustrated in Figs. 2, 3 and 4, is especially adapted for use in the formation of walls, but by making slight changes, the basket or container may also be employed in the formation'of girders. It is only necessary to provide a bottom for the container or reinforcement forth'e lower portion of theconcrete of the girder.

In Fig. 9, I have illustrated a portion of a container especially adapted for use in the formation of girders. In this container, I provide a channel member 30 integral with the two oppositely-disposed vertically-extending channel members 21 of the two side wall sections. At the intersection of the channel member'30 and the two side chan nel members 21", the flanges are cut to cr mit the webs to be bent to substantial y a right angle. The side wall sections, save for being integral with the bottom, are formed the same as the side wall sections shown in Figs. 2,3 and 4. The channels serve to support the rods 20 and the channels are spaced apart by the. longitudinally-disposed members 24.- The channel members30 of the bottom serve to support a plurality of longitudinally-attending rods 31, 's aced apart the desired distance to provide t e necessary angle to each other. The rods 20 of one side wall section are bent at the desired angle and constitute the rods of the side wall section of the intersecting concrete girder or partition Wall. In forming the reinforcement for floors, I

utilize substantiall the same elements as I do in forming co umns, girders and walls.

In Fig. 14, I have illustrated a reinforcement for floors formed of a plurality f rods 31 extending through the flanges o1 shanncls 30 and the channels are s aced apart and held parallel by longitudina ly-disposed bars 24 of strap iron. In forming a floor, I

provide a plurality of reinforcement sections,

as shown in Fig. 14, each section being of a width convenient to handle and having. the rods31 of a length sufficient to extend-from the outer surface of one wall or girder to the opposite side of the adjacent wall or girder. lhe ends of the rodslil are extended be neath the longitudinally-disposed bars 24 of the walls or girders between which the floor is to extend, and the ends of the; rods 31' are provided with downturnedterminal por- 'are not necessarilylso close together asto prevent the passage of concrete therethrough, as 1 preferably provide a temporary plat form or support beneath the reinforcement to hold up the concrete while it is hardening.

The rods forming the sides of the container may be'of any size desired, dependent upon the amount of reinforcement necessary and the plasticityyof the concrete to be em.

ployed.' If desired, ch wall section may be made u of a p urality of successive layers of ror s, the rods of one layer being arranged zigza to the rodsbf'thenextlayer, as shown 1nig.'10. Theinner'row of rods 20' may, if'desire'd, be further apart and of larger size than the outer series of rods 20. The inner series of rods would prevent the passage of the coarser portions of the concrete" therethrough and the outer series of rods would resist the'passagc ofth'e finer portion ofthe concrete or cement.

lt'is understood that where the strut-midi particularly the girders, is to sustain great wear and more thanordinary reinforcement is necessary to resist the tension, I may utilize in the containers (for, the girders any well-known type of reinforcing bar, but the 3 closely adjacent use of such bars would'not affectthe construction, ;operation, or advantages of my; improved system hereinabove described. At the time the concrete is placed in the hontainers, the small portion of cement escapin' between the adjacent rods may he smoothe with a trowel to provide a finishing coat and; to entirely conceal the wall sections of the containers, or, if desired, the cement may be left in ridges between the rods until after it has hardened, and an outer finishing layer", 'of'cement or mortar ap to form a smooth su ace. This. coating will be firmlyheld in place by reason of the rough nature of the exposed surface of the reinforcement andthe ridges of concrete extending outwardly between the rods thereof. Having thus described my invention, I claim as new and desire to secure by'Letters Patent:
